JUTE-MACHINE.

SPECIFICATION forming part ofLette rs Patent No. 312,100, dated February10, 1885. Application filed October 15, 1854. (No model.)

To all whom it may concern.-

Be it known that I, JOHN G. DELAVIGNE, of the city of New Orleans, inthe parish of Or- 4 leans, State of Louisiana, haveinvented-a new andImproved Jute-Machine, of which the following is a full, clear, andexact description.

The object of my invention is the separation and extraction of the woodyfibers from dry jute and ram'ie without wetting or soaking the stalks,asis usual, thereby avoiding the objec-V tions that exist to working thejute or ramie in a green state.

In carrying outmy invention thegreeu stalks are subjected to a heatingand fermenting process,and then after drying are run through themachine, as hereinafter described and claimed.

Reference is to be had to the accompanying drawings,forminga part ofthisspecification,in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 is a plan view, partly sectional, and Fig. 2 is a longitudinalsection,ofthe machine.

A is the table or bed, provided at one end .with a platform, a, forreceiving the stalks.

B B are corrugated rollers fitted transversely of the bed in suitablebearings, one roller being above and the other below the bed.

0 is a heavy plate sustained across the bed -above a depression, D, bysupports at its ends, which are operated by eccentrics t,that give arising and falling motion to the plate.

E E are feeders, made as blades with sawteeth and operated by eccentricse,so as to act through slots in the bed to give a forward movement tothe crushed material.

F F are beaters hung on rock-shafts f, and fitted for operation inalternate order, so as to beat the material.

G G are smooth delivery-rollers at the-end of bed A, geared together anddriven by a chain from the shaft of the upper roller, B.

H is a rotary brush placed in front of roller G,and operated by thegear-wheel on the upper roller.

In order to prepare the jute and ramie for the machine, the green stalksare piled up in the field and left to heat and ferment, so as toseparate the gum, sap, or albumen from the fiber. They are then stackedaway until dry, U

when they are ready for the machine.

The stalks are fed to the machine on platform a, and, passing betweenrollers B, are crushed. The plate or crusher G acts on the crushedmaterial to cause a still further crushing and separation, and theheaters F,striking the material as it moves over the bed, separate thewoody substances, dust, and trash from the fiber. The brush H throws offthe dust and trash,and the fibers, passing between the rollers G, aredelivered in the form of a ribbon. In this manner the fibers areseparated from the dry stalks, the usual netting is not required, and itis not necessary to operate on the green stalks, as they can be kept forany length of time.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The combination, in a jute-machine, of corrugatedrollers B, reciprocating crusher O, beaters F, brush H, anddelivery-roller G, substantially as described.

2. In a jute-machine, the reciprocating plate 0, combined withcrushing-rollers B and bed having depression D, substantially as and forthe purpose specified.

3. In a jute-machine, the vibrating feeders E, formed with saw-teeth,combined with slotted bed A, for operation as specified.
